I know this thread is likely not serious (or if so, then I beg to differ!) but the chambering window is so small that even if it is sometimes done without purpose, it is too rare to be a problem.
If say, to chamber you had x3 as much time as you have right now, then the problem would be exponentially more apparent when fighting spammers: a good spam is also a technique, but if spamming mindlessly was becoming too good on a risk/reward formula (if chambering was very easy while spamming (+ combo breaking feinters)), then the game would reward beginners and punish excellent fighters way too much and I would join the idea of (not removing) nerfing chambering by making it harder to pull off.
Atm chambering is at a very nice sweet spot: if you have played the game a lot you can pull it off often if properly focused and good anticipation + the slowest/most powerful weapons somewhat benefit from it + the fastest weapons can still be counter-chambered (or just blocked) if perfect positioning. There is no real exploit possible and skill is properly rewarded.
